plot_google_map.m uses the Google Maps API to plot a map in the background of the current figure.
It assumes the coordinates of the current figure are in the WGS84 datum, and uses a conversion code to convert and project the image from the coordinate system used by Google into WGS84 coordinates.
The zoom level of the map is automatically determined to cover the entire area of the figure. Additionally, it has the option to auto-refresh the map upon zooming in the figure, revealing more details as one zooms in.
The following code produces the screenshot:
lat = [48.8708 51.5188 41.9260 40.4312 52.523 37.982];
lon = [2.4131 -0.1300 12.4951 -3.6788 13.415 23.715];
plot(lon,lat,'.r','MarkerSize',20)
plot_google_map('maptype','roadmap')
Known Issues:
1) The resolution of the maps downloaded via the API is limited to 640 pixels. Since a portion of the downloaded map is usually outside the current axis zoom, this results in a slightly pixelated rendering.
2) The static maps API is limited to 1000 requests per day. If you use this function a lot, consider disabling the auto-refresh upon zoom option.
Note:
The Static Maps V2 API no longer requires an API key. |
